Frequently Asked Questions

What’s the most common disease issue for Spanish Roja garlic (Allium sativum var. ophioscorodon), and how do I stop it?
Watch for white rot (Sclerotium cepivorum), which causes yellowing and sudden plant collapse, often with a white fungal growth at the base and garlic roots. Remove and discard infected plants, don’t compost them, and keep the bed from staying wet—improve drainage and avoid replanting garlic/Allium in the same spot for several years. If you’ve had white rot before, start with clean cloves and keep weeds down to reduce stress during the long 240-day season.
How often should I water Spanish Roja garlic during the main growing phase?
During active bulbing (roughly mid-season), water deeply about once per week only if the top 1 inch of soil dries out—aim for consistently moist but not saturated soil. Stop routine watering when the lower leaves start to yellow and most plants are nearing maturity, so cloves can cure instead of rotting. In heavy clay, reduce frequency to prevent staying wet around the shallow root zone.

Sowing Tips

Soil Temperature

Direct sow or transplant when soil at planting depth holds 40°F for reliable germination and early growth.

Expert Note

Plant hardneck garlic in fall so it establishes a strong root system before winter, then vernalizes for a spring harvest.
